STEAM-TRAP.

Application filed January 26, 1914, Serial No.'814,435.

To all whom t may concern Be it known that I, WILLIAM `17V. MonGAN, Jr.,a citizen of the United States, reslding in Philadelphia, Pennsylvania,have invented certain Improvements in Steam- Traps, of which thefollowing is a specification.

One object of my invenion is to improve the construction of a steam trapof the type which is controlled by a tube having a sensitive liquidtherein.

A further object of the invention is to arrange the valve so that it canbe readlly removed and adjusted.

A further object is to firmly securing the rear end of the tube to thecasing and yet allowing for ready removal for adjustment and repairs.

These objects I attain in the following manner, reference being had tothe accompanying drawings, in which 1- i Figure 1, is a perspective viewof my.1m proved steam trap; Fig. 2, is a longitudinal sectional view onthe line L -a, Fig. 3; Fig. 3, is a transverse sectional view on theline 6 6, Fig. 2; Fig. 4, is a perspective view of the valve and itscarrier; Fig. 5, is a perspective view showing the socket for the rearend of the tube; and Fig. 6, is a view of a modication of the means forattaching the rear end of the tube to the casing.

The casing is in the general form of a sphere and made in two parts, thelower part 1 carries the mechanism and the upper part 2 forms theinclosing cap. In the present instance, the lower part 1 has an internalscrew thread and the cap 2 has an external screw thread, so that, whenthe two parts are coupled together by screwing one into the other, asteam tight joint, which will not suck air under vacuum, is produced andgaskets are dispensed wit 3 is an outlet in the bottom section 1 and 4is an inlet, and in this inlet opening is a nozzle 5 which is securedfirmly therein and projects into the steam chamber, as shown, to act asa support for the valve carrier 6, so that the carrier is free to moveunder the action of the U-shaped tube 7 which is hollow and whichcontains the liquid which is influenced by the changes in temperature.The carrier snugly fits the projecting portion of the nozzle which is inthe form of a sharp valve seat. Mounted in the carrier is a screwthreaded valve stem 8 having a provide means for vcasing having an inletand an outlet, the

valve 9 with a rounded end, as shown, which ts against the valve seat atthe end of the nozzle. There isa nut on the valve stem to lock the valvein the position to which it is adjusted.

The carrier is grooved for the reception of the forked end 10 of theU-shaped tube, so as to cause the carrierto move with the tube, as abovedescribed. The rear end of the tube has a hooked end 11, in the presentInstance, which engages a ledge 12 on the casing, and projecting fromthe casing at each side of the tube are ears 13 having eX- tensions 14to retain the hooked end 0I the tube in position when the tube engagesthe valve carrier. The hooked end of the tube is so formed that when theopposite end is raised the hook will disengage the ledge and can bereadily removed. In some instances a screw 15 "may be used which extendsthrough a cross bar 16 of the casing and through an opening in the endof the tube, as illustrated in Fig. 6. The screw may have a slotted heador a head adapted to receive a wrench as desired.

It will be seen on referring to Figs. 2 and 6 that the rear end of thecurved tube 7 is engaged by a device which does not extend through thecasing so that the leakage is avoided at this point.

By making the trap as above described, I am enabled t0 readily dismantleit and to adjust the valve after it has been detached from the casingand, furthermore, by making the casing in the general form of a sphereand of large area, I provide for the ready cooling of the tube when thesteam is cut off, making it more sensitive than where the space islimited.

A steam trap of the type above described is used for any character ofheating unit for regulating the flow of steam therefrom and, in manyinstances, these traps are located in places where they are not easy ofvaccess, consequently by making the valve carrier detachable it can beremoved and the valve adjusted to a nicety, and the carrier re-appliedwithout trouble, insuring more accuracy in the adjustment than if thevalve was not detachable from the casing.

I claim:

1. The combination in a steam trap, of a 1nlet being at one side of thecasing; a fixed Specification ofrLetters Patent. Patented July 11, 1916.

tubular nozzle secured to the body of the casing and inline with theinlet opening and projecting into the chamber randclosed by the casing,the kinner end of the tubular nozzle forming a valve seat; a valvecarriery surrounding the tubular nozzle andu arranged to slide, thereonand extending beyond the valve seat; a valve mounted Within the carrierin line With the tubularnozzle and arranged to close against the seat atthe end of saidfnozzle; and a curvedvtube detachably secured to thecasing at one end andarranged to .detachably engage the valve carrierattheopposite end; the'movement of the carrier and its Valve beingcontrolled by the tube.

2.V They combinationin a steam trap, of a two-part casing, one parthaving an inlet atlet'opening; a U-shaped tube controlling the movementof the valve and having a projection at one endarranged to enter andrest.

in the integral projection and forked at the opposite end to engage thevalve carrier.

In testimony whereof,l I have signed my name to thiscspecilication,inthe presence of two subscribing Witnesses.
